Schneider Electric TSX 17 10/20 DMF 342A Product Description

Schneider Electric TSX 17 10/20 DMF 342A is a dedicated I/O expansion unit for TSX17-10/20 Micro PLC series in industrial automation systems. This I/O expansion unit provides 34 combined digital input and relay output channels to extend the original PLC I/O capacity. The compact I/O expansion unit connects to TSX17 main controller via extension cable for fast integration. This I/O expansion unit expands signal points for machine start-stop, sensor feedback and actuator control loops.

TSX 17 10/20 DMF 342A delivers reliable discrete signal processing for field digital input and relay output signals. Precise discrete signal processing collects on/off signals from limit switches, photoelectric sensors and safety interlocks. Stable discrete signal processing drives contactors, solenoid valves and indicator lights through relay contacts. Dependable discrete signal processing supports frequent cyclic operation in continuous manufacturing environments.

This unit features built-in relay output contacts with low switching load capacity for control circuit loads. The durable relay output contacts support 120/240VAC working voltage for machine control circuits. The isolated relay output contacts separate PLC internal logic from field high-voltage control loads. This robust relay output contacts simplifies wiring and improves circuit safety for machine interlock.

TSX 17 10/20 DMF 342A is widely used in machine tools, packaging lines, conveyor systems and textile automation equipment. It is equipped with LED channel indicators for rapid fault diagnosis and status checking. It is a discontinued original spare part for renovation and maintenance of legacy TSX17 Micro PLC control systems.
